What Are the Key Strategies for Developing Safer Nanomaterials?
Several strategies are employed to develop safer nanomaterials, including:
1. Surface Modification: Altering the surface properties of nanomaterials can reduce toxicity. For instance, coating nanoparticles with biocompatible materials can enhance their safety profile.
2. Green Synthesis: Using eco-friendly methods for nanomaterial synthesis reduces environmental impact. For example, utilizing plant extracts or microorganisms can produce nanoparticles in a sustainable manner.
3. Biodegradable Nanomaterials: Developing materials that can break down into non-toxic byproducts reduces long-term environmental risks. Polylactic acid (PLA) and other biodegradable polymers are examples.
4. Comprehensive Risk Assessment: Conducting thorough risk assessments during the design phase can identify potential hazards and mitigate them early.
